Pre‐college advising programs exist in most disadvantaged high schools throughout the United States. These programs supplement traditional advising by high school guidance counselors and attempt to help underrepresented and disadvantaged students overcome the complexities of the postsecondary admission and financial aid processes. Existing evidence on these programs often uses within‐school randomization where spillovers and alternative supports may confound estimates. We provide the first evidence on a whole school intervention resulting from a school‐level randomized controlled trial in the United States. The college access program we study uses a near‐peer model where a recent college graduate works at the school assisting students in the application and enrollment process. Pooled results across the first three years of program implementation find no significant impacts on overall college enrollment. However, subgroup analyses reveal positive, significant effects among the groups most targeted by the intervention: Hispanic and low‐income students. Most of the impact comes through increasing two‐year college enrollment, but this appears to be new entrants rather than inducing students to move from four‐year to two‐year colleges. The observed positive effects for these subgroups attenuate over time. We attribute this drop in the estimated impact to departures in fidelity of the experiment. Even among the cohorts for which we find positive enrollment impacts, we find no significant impacts on college persistence.  相似文献

Giorgios Kallis argues that Degrowth, as a pluralistic convergence of both theoretical perspectives and social movements, is part of a renewal of the critique of capitalism based on the ecological contradictions of this social order. In “Socialism without Growth” Kallis engages with other, more classical, approaches that have examined the contradictions of capitalism and the material conditions for a future, ecologically viable postcapitalist social order. After a quick exposition of the lineaments of a general theory of surplus and accumulation based on Bataille, Polanyi and Georgescu-Roegen, Kallis mobilizes Marx’s theory of accumulation to examine the growth drivers of capitalism. I will argue that economic growth in advanced capitalism can best be explained as a relation that articulates capitalist overproduction to overconsumption, and outline some analytical tools that such an explanation can provide to those interested in understanding the specific growth drivers of contemporary capitalism and their social and ecological consequences. This implies moving beyond the model outlined by Marx and mobilizing concepts and categories developed by the over-accumulation approach to capitalism, those developed by some of Degrowth’s most vocal Marxist critics, such as Foster. Through my dialogue with Kallis I will try and bridge these two approaches.  相似文献

This study examines the effects of chronic (i.e., repeated and cumulative) mediated exposure to political violence on ideological beliefs regarding political conflict. It centers on these effects on young viewers, from preadolescents to adolescents. Ideological beliefs refers here to support of war, perception of threat to one’s nation, and normative beliefs concerning aggression toward the out-group. A longitudinal study was conducted on a sample of Israeli and Palestinian youths who experience the Israeli-Palestinian conflict firsthand (N = 1,207). Two alternative hypotheses were tested: that chronic exposure via the media increases support for war and aggression and elevates feeling of threat, or that chronic exposure via the media strengthens preexisting beliefs. Results demonstrated that higher levels of exposure were longitudinally related to stronger support for war. Regarding normative beliefs about aggression and threat to one’s nation, mediated exposure reinforced initial beliefs, rendering the youths more extreme in their attitudes. These results mostly support the conceptualization of the relation between media violence and behaviors as “reciprocally determined” or “reinforcing spirals.” The results are also discussed in light of the differences found between the effect of exposure to political violence firsthand and exposure via the media.  相似文献

Facial cues are consequential for voters’ behavior at the polls. Yet the facial cues that are associated with vote choice remain under-examined. We predicted that vote choice judgments rely, in part, on the sex typicality of facial cues (i.e., the degree of facial masculinity and femininity) that vary as a function of candidate gender and partisan identification. Stimuli included image pairs of winners and runners-up in the elections for the 111th U.S. House of Representatives. In Study 1, we found that female Republican candidates who appeared relatively more feminine and male Republican candidates who looked relatively less masculine in their appearance were more likely to win their election. Democratic candidates’ electoral success was not related to their sex typicality. In Study 2, we found that relatively masculine-appearing Democrats and feminine-appearing Republicans were more likely to be selected in a hypothetical vote choice task. Implications for U.S. partisan politics are discussed.  相似文献

Nationwide, law enforcement professionals have endured increasing scrutiny regarding their treatment of custodial suspects and their alleged abridgement of suspects’ Constitutional rights. At the same time, in the interests of community safety, many members of the public fully expect police officers to function efficiently in arresting and facilitating the prosecution of likely perpetrators. These perspectives reflect due-process and crime-control models respectively. Very little is known, however, about how law enforcement professionals actually view the rights of the accused when not acutely immersed in the cross-currents of public opinion. Using an anonymous survey, the current investigation addresses both Miranda rights as well as the European Union’s (EU) much more comprehensive approach to the rights of the accused. In general, this sample of 209 urban police officers favored protections of criminal suspects that went considerably beyond Miranda safeguards.  相似文献

Objectives

To evaluate whether the 1990s crime drop reflects a decrease in offending prevalence (the fraction of the population engaged in crime), offending incidence (the frequency of offending among active criminals), or some combination of the two.

Methods

We use individual-level longitudinal data on adolescent offending patterns from the Pittsburgh Youth study (PYS), integrating information from the youngest and oldest cohorts to compare offending among 17–18 year old males at the beginning and end of the 1990s. Logistic and negative binomial regression models are estimated to assess whether there are significant differences in offending prevalence and incidence during the 1990s.

Results

The reduction in property crime rates in the PYS sample during the 1990s can be attributed to declines in both offending prevalence and incidence. The overall decline in serious violence during the 1990s for the full sample was primarily the result of a falloff in prevalence. However, for black youth our results indicate significant reductions in both the prevalence and incidence of serious violence. We did not detect a significant difference in illegal drug sales during the period.

Conclusions

Using longitudinal data on individuals to decompose aggregate crime trends into changes in the prevalence and incidence of offending offers insights into the nature of the 1990s crime drop that cannot be discerned from aggregate crime data. Future research should build on the current study by examining the specific mechanisms that influence change over time in crime prevalence, incidence, or both.
